What are CFA Authorized Calculators?

CFA authorized calculators are specific financial calculators approved by the CFA Institute for use during the Chartered Financial Analyst (CFA) exam. Unlike many other professional exams that allow a broader range of scientific or financial calculators, the CFA exam has a strict policy, permitting only two models: the Texas Instruments BA II Plus (including the Professional version) and the Hewlett Packard 12C (including its various Platinum and anniversary editions).

This stringent policy ensures a level playing field for all candidates, preventing any unfair advantage from more advanced or programmable calculators. Understanding and mastering one of these CFA authorized calculators is not just a recommendation; it’s a fundamental requirement for success in the exam, as many questions require time value of money (TVM), cash flow analysis, and statistical computations that are efficiently solved using these tools.

Who Should Use CFA Authorized Calculators?

• CFA Candidates: Anyone preparing for or taking the CFA Level I, II, or III exams MUST use one of these approved calculators.
• Finance Students: Students pursuing degrees in finance, accounting, or economics can benefit from learning these calculators early, as they are industry standards.
• Financial Professionals: Investment analysts, portfolio managers, and financial planners often use these calculators for quick, on-the-go calculations.

Common Misconceptions about CFA Authorized Calculators:

• “Any financial calculator will do.” Absolutely not. Only the specific models mentioned are allowed. Bringing an unauthorized calculator will result in its confiscation and potential disqualification.
• “The calculator will do all the work for me.” While powerful, these calculators are tools. You need to understand the underlying financial concepts and formulas to input data correctly and interpret results.
• “The BA II Plus Professional is significantly better than the standard BA II Plus.” While the Professional version has a few extra functions (like Net Future Value and Modified Internal Rate of Return), for the vast majority of CFA exam questions, the standard BA II Plus is perfectly adequate. The core functionality is the same.
• “The HP 12C is outdated.” The HP 12C, despite its age, remains a highly capable financial calculator, especially favored by those who prefer its Reverse Polish Notation (RPN) entry system for its efficiency.

CFA Authorized Calculators: Feature Comparison and Scoring Logic

Our recommendation tool uses a scoring system to help you decide between the two CFA authorized calculators. Below is a detailed breakdown of the features considered and how points are assigned.

Key Factors That Affect Your CFA Authorized Calculator Choice

While both CFA authorized calculators are highly capable, several factors can influence which one is the better fit for you. Considering these aspects will help you make an informed decision.

1. Entry System (Algebraic vs. RPN): This is arguably the most significant differentiator. The BA II Plus uses algebraic entry, which is intuitive for most users familiar with standard calculators. The HP 12C uses Reverse Polish Notation (RPN), which requires a different way of thinking (operands first, then operator). While RPN can be faster and more efficient once mastered, it has a steeper initial learning curve. Your comfort with either system is paramount.
2. Learning Curve and Time Investment: If you’re short on time or prefer a calculator that feels familiar from the start, the BA II Plus might be preferable. If you have ample time to practice and are willing to invest in mastering a potentially more efficient system, the HP 12C’s RPN could be a long-term advantage.
3. Cost and Budget: The standard Texas Instruments BA II Plus is generally the most affordable option among the CFA authorized calculators. The BA II Plus Professional and various HP 12C models can be significantly more expensive. Your budget can play a role, especially if you’re a student.
4. Display and Readability: Both calculators have single-line displays. The BA II Plus typically shows fewer digits and is more straightforward. The HP 12C, especially with RPN, might display more context or stack registers, which some users find helpful, while others might find it less intuitive initially.
5. Key Layout and Ergonomics: The BA II Plus has a more traditional scientific calculator layout. The HP 12C has a distinct, financial-focused layout with many functions accessed via shift keys. Personal preference for key feel, size, and layout can impact speed and comfort during the exam.
6. Availability and Accessories: Both calculators are widely available. Consider factors like battery life (HP 12C is known for extremely long battery life), availability of protective cases, and ease of finding replacements if needed.
7. Prior Experience: If you’ve used a BA II Plus or HP 12C in previous finance courses or work, sticking with what you know can save valuable study time and reduce exam-day stress.

Carefully weighing these factors will guide you to the CFA authorized calculator that best suits your individual needs and maximizes your chances of success on the CFA exam.

Frequently Asked Questions (FAQ) about CFA Authorized Calculators

Q1: Can I use any financial calculator for the CFA exam?

No. The CFA Institute has a very strict policy. Only two models of CFA authorized calculators are permitted: the Texas Instruments BA II Plus (including the Professional version) and the Hewlett Packard 12C (including its Platinum and anniversary editions).

Q2: What happens if I bring an unauthorized calculator to the exam?

Your unauthorized calculator will be confiscated, and you may be disqualified from the exam. It’s crucial to double-check that your calculator is one of the approved CFA authorized calculators before exam day.

Q3: Is the BA II Plus Professional significantly better than the standard BA II Plus?

For the vast majority of CFA exam questions, the standard BA II Plus is perfectly sufficient. The Professional version offers a few additional functions (like Net Future Value and Modified Internal Rate of Return) and a slightly better build quality, but these are rarely critical for exam success. The core functionality for TVM, cash flow, and statistics is identical.

Q4: Is the HP 12C difficult to learn because of RPN?
